Is something wrong with my AS substrate?

I just set up this tank with Aqua Soil Amazonia II regular type. It appears that when the substrate breaks apart, the inside is lighter in color than the outside. I haven't seen this in anyone else's pictures.

Also, some of my stem plants are melting below the substrate while they look OK above the substrate. Anyone else have this happen? Did I get a bad batch of substrate? The tank is only two weeks old and is still cycling.

2 week old aquasoil should not be breaking apart. Have you been constantly re-scaping? There were some known issues with Amazonia II. Suggest you contact whoever you bought it from, describe the problem, show them the pictures. I have read a number of posts where people have gotten the bad batches of aquasoil replaced.

Not unusual to have some melting until the aquasoil cycles and the plants settle in. Are you doing at least bi-weekly water changes to reduce ammonia build up?

While it is not necessary to dose ferts in a new aquasoil setup ADA recommends using Brighty K initially which is a potassium supplement. Would not hurt for you to at least be dosing K2SO4 (potassium sulfate).

I haven't done any rescaping since the initial setup. The substrate looked like that from the get-go.

I've only changed water once. The reason I haven't been changing water is that I wanted the tank to cycle first. Ammonia is at 4.0 right now.

You do not need to stop water changes for cycling .. With this load of Ammonia, you are very likely prone to have large algae attacks .. specially green water... Please start doing water changes.. typically with Amazonia II, this is the routine i follow..
1. First week - daily 25 - 30% WC
2. Second Week and third week - 50% every alternate days
3. 4th and fifth week - 50% every 2 days
5. Thereafter from 6th week, weekly once 50% ....

If you have used Bacter 100, you may get away by doing smaller water changes.. but to be on the safer side.. make WC..

On a newly setup tank, when plants are still settling in.. no water changes, and high ammonia is a dangerous recipe for disaster...

So dose Brighty K and Step 1 regularly, along with water changes...

Amazonia II is more porous specially the regular gravel and it breaks showing slight orange colour at inside... which is normal ... if you dislike the coloration or worried, go for the finer gravel of amazonia II...

I think you got a bad batch of AS2. The same thing happened to my ada as2 once i added water. The as2 would just dissolve into red pebbles and I'll end up with black mud with red pebbles. I was lucky enough to have ordered the Ada as2 from Jeff over at adgshop who provided excellent customer service. Jeff replaced my ada as2 with as1. I think the as1 is so much better than the as2. good luck and hopefully you get your problem resolved.

I am going through this right now with my nano setup. As soon as I added the water the soil turned orangish in color. Terrible.
